Improving Energy Efficiency
Efficient energy management is a key issue in the world’s attempts to save energy, reduce greenhouse gas emissions and deal with climate change challenges. At Infineon, energy is used mainly in the form of electricity at all steps of semiconductor manufacturing. Primary energy sources, such as oil and gas, play only a minor part.
The majority of energy is consumed in our frontend manufacturing sites. There, energy is required to operate the production equipment, and also to maintain highly sophisticated physical conditions, such as the particularly necessary stable climatic conditions in Infineon’s cleanrooms. Due to their nature, backend processes require far less energy than frontend processes, followed by the development and office sites, which consume the smallest percentage.
We have implemented the systematic energy management system standard, ISO 50001, at our main manufacturing sites. Improving energy efficiency means reducing specific energy consumption, this is the energy consumed per manufactured production unit.
Infineon’s global energy efficiency program “Energy 2015” applies to all sites and help us to identify and implement further areas of potential improvement. Therefore, we are continuously analyzing options for boosting energy efficiency and adopting, whenever possible, renewable energy sources at our sites.
